SYSTEMD-....SERVICE(8) systemd-veritysetup@.serviceSYSTEMD-....SERVICE(8)

NAME         top

       systemd-veritysetup@.service, systemd-veritysetup - Disk verity
       protection logic

SYNOPSIS         top

       systemd-veritysetup@.service

       /usr/lib/systemd/systemd-veritysetup

DESCRIPTION         top

       systemd-veritysetup@.service is a service responsible for setting
       up verity protection block devices. It should be instantiated for
       each device that requires verity protection.

       At early boot and when the system manager configuration is
       reloaded kernel command line configuration for verity protected
       block devices is translated into systemd-veritysetup@.service
       units by systemd-veritysetup-generator(8).

       systemd-veritysetup@.service calls systemd-veritysetup.

COMMANDS         top

       The following commands are understood by systemd-veritysetup:

       attach volume datadevice hashdevice roothash [option...]
           Create a block device volume using datadevice and hashdevice
           as the backing devices.  roothash forms the root of the tree
           of hashes stored on hashdevice. See Kernel dm-verity[1]
           documentation for details.

           Added in version 250.

       detach volume
           Detach (destroy) the block device volume.

           Added in version 250.

       help
           Print short information about command syntax.

           Added in version 250.
